Background:The incidence of duodenal Brunner’s gland hyperplasia is low and the etiology and pathogenesis has not yet been clarified. Aims:To investigate the relationship between duodenal Brunner’s gland hyperplasia and Helicobacter pylori( Hp ) infection. Methods:A total of 96 patients with duodenal Brunner ’s gland hyperplasia diagnosed by pathological examination from October 2005 to December 2013 at People’s Hospital of Xinjiang Uygur Autonomous Region were enrolled in this study,and 270 cases without duodenal Brunner’s gland hyperplasia were served as controls. Hp infection was detected by 14 C-urea breath test( 14 C-UBT). The relationship between duodenal Brunner’s gland hyperplasia and Hp infection was analyzed. Results:In the duodenal Brunner ’s gland hyperplasia group,75 patients were Hp positive,the proportion of Hp infection was 3. 57( 75/21 ). In the control group,110 cases were Hp positive,the proportion of Hp infection was 1. 45(160/110). The difference between the two groups was statistically significant(χ2 =10. 97,P=0. 001). Hp infection was a risk factor of the genesis of duodenal Brunner’s gland hyperplasia( OR=2. 46, 95% CI:1. 44-4. 19). Conclusions:Hp infection may be related with the genesis of duodenal Brunner’s gland hyperplasia.

BACKGROUND: Resveratrol is a naturally occurring phytoalexin present in grapes, peanut and some herbs. It has been demonstrated to produce a variety of biological actions, such as anticancer, antiinflammation. Accumulating line of evidence supported the view that resveratrol may exert protective effect on cardiovascular system. However, its protective mechanism is not completely understood.OBJECTIVE: To investigate the anti-ischemic effect and mechanism of resveratrol (Res) on acute myocardial infarction in rats.DESIGN: Randomly grouping paralleled control study.SETTING: Pharmacological Laboratory of Harbin Medical University, Biopharmaceutical Key Laboratory of Heilongjiang Province-Incubator of State Key Laboratory.MATERIALS: The experiment was carried out in Department of Pharmacology of Harbin Medical University from March 2005 to July 2005.Totally 80 male Wistar rats weighting 250-300 g were selected in this study. Among them, 60 rats after operation successful modeling were randomly grouped into 5 groups: sham operation group, blank control group,resveratrol 5 mg/kg, 15 mg/kg and 45 mg/kg groups with 12 in each group.METHODS: Acute myocardial infarction (AMI) model was induced by ligation of the anterior branch of the left coronary artery in rat, Sham operation group: The same suture was put through but not ligated. Resveratrol group: Rats were injected with 5, 15 and 45 resveratrol mg/kg provided by Hunan Huaguang Biological Products Company Limited (batch number: 20050221, purity ≥99%) and ligated after 10 minutes. Model group: The same volume saline was injected for 10 minutes and then rats were ligated. Observe and record ST segment of standard limb lead Ⅱ electrocardiogram (ECG)after 1, 5, 10, 15, 30 minutes after ligating the left anterior decendingcoronary artery. After 6-hour ischemia, the infarct size areas was identified with the myocardium by 2, 3, 5-triphenyltetrazolium chloride (TTC) stain; the activities of serum .creatine kinase (CK)and lactate dehydrogenase (LDH) were determined by spectrophotometric method; the apoptosis in cardiomyocyte was detected by d-UTP end labeling method mediated with tagged deoxynucleotide transferase in situ (TUNEL); apoptosis-related proteins of Bcl-2, Bax and Fas expression were measured with estreptomicina avidin peroxidase chain. Measurement data were compared with t test.MAIN OUTCOME MEATURES: ST increase; the activities of serum creatine kinase (CK) and lactate dehydrogenase (LDH); the infarct size areas and the apoptosis rate in cardiomyocyte; the. expression of apoptosis-related proteins of Bcl-2, Bax and Fas.RESULTS: All of the 60 rats entered the final analysis. ① ST segment raise in high dosage group was lower than that in model group 1, 5 and 10 minutes after ligation (P ＜ 0.05), and it was also lower than that in model 15 and 30 minutes after ligation (P ＜ 0.05). This effect was dose-dependent. ② Infarct size in each dosage group was smaller than that in model group (P ＜ 0.05). This effect was dose-dependent. ③ The activities of CK and LDH in different dosages of resveratrol groups were significantly lower than those in model group (P ＜ 0.05). This effect was dose-dependent. ④ Apoptosis index in model group was higher than different dosages of resveratrol groups (P ＜ 0.05); The expression levels of Bax and Fas proteins in model group were higher than those in high and middle dosages of resveratrol groups (P ＜ 0.05); The expression level of Bcl-2 protein was lower than that in high and middle dosges of resveratrol groups (P ＜ 0.05).These effects were dose-dependent.CONCLUSION: Resveratrol can protect acute myocardial ischemic injury induced by coronary artery of ligated rats, and the effect is dose-dependent.Effect of resveratrol on myocardial ischemia is related to adjusting expressions of Fas, Bcl-2 and Bax and inhibiting myocardial apoptosis.

OBJECTIVETo observe the clinical efficacy on senile female bladder neck obstruction treated with acupoint application, therapy and western medication.

METHODSFifty cases of senile female bladder neck observation were randomized into an obstrvation group and a control group, 25 cases in each one. Tamsulosin hydrochloride capsules were taken orally in the two groups, 0.2 mg every night, continuously for 100 days. In the observation group, with radix aconiti lateralis preparata, semen brassicae and fructus ligustri lucidi contained, bushentongyu plaster was used at Shenque (CV 8), Sanyinjiao (SP 6), Pangguangshu (BL 28), Zhongji (CV 3) and Sanjiaoshu (BL 22), once every two days. Eight treatments made one session and 6 sessions were required totally. The international prostate symptom score (IPSS), the bother score (BS), the residual volume (RV) and the maximal urinary flow rate (MFR) were observed before and after treatment in the two groups. The clinical efficacy was compared between the two groups.

RESULTSEvery score in IPSS after treatment was reduced apparently as compared with that before treatment in the two groups (all P < 0.01). The improvements in feeling of incomplete, bladder emptying, intermittency < 2 h, urgency, interupted urination and nocturia in the observation group were more advantageous than those in the control group (all P < 0.05). The total effective rate was 95.65% (22/23) in the observation group, higher than 85.71% (18/21) in the control group (P < 0.05). After treatment, RV, MFR and BS were significantly different as compared with those before treatment (all P < 0.05).

CONCLUSIONThe combined therapy of acupoint application of bushentongyu plaster and oral administration of tamsulosin hydrochloride capsules achieves the significant efficacy on senile female bladder neck obstruction as compared with the simple administration of tamsulosin hydrochloride capsules.
